A Marchman Act petition asks a Florida court to consider involuntary treatment for substance abuse. A petition alone does not put anyone into treatment. Only a judge can order that, after a hearing and proof that meets the statute. This page offers general information about involuntary treatment petitions in Florida.
When Your Spouse’s Addiction Has Made Home Unpredictable
The court process in Chapter 397 can bring a spouse before a judge, but it has firm limits. Those limits matter most when home already feels unsafe.
You may be dealing with late-night incidents, money that disappears and children who see more than they should. You may feel like you are holding the whole household together alone. That weight is real. It makes sense to understand the law clearly before you decide on a next step.
This page is general legal information, not advice about your family’s facts. The outcome in any case depends on the facts. It answers one question: what can a Chapter 397 involuntary treatment petition do, and what can it not do?
If your spouse's drinking or drug use has made home feel unpredictable, you don't have to work out the options alone, and the team at Robinson Casey can talk it through with you. Talk it through with our team — the first consultation is free, confidential, and carries no obligation.

What Chapter 397 Covers and Who It Is For
The Marchman Act is the part of Chapter 397 that handles involuntary treatment for substance use.
The statute also says who can start the process. For an adult, a petition may be filed by the spouse or legal guardian, any relative, a service provider, or an adult with direct personal knowledge of the respondent’s substance abuse impairment and his or her prior course of assessment and treatment. When the person struggling with substance abuse is your adult spouse, Florida law includes you among those who may file a petition for involuntary treatment services.
Mental health crises follow a different track. The Baker Act is a separate law for involuntary examination tied to mental illness. The Highlands County Clerk’s Baker Act page covers that process. Many families face both problems at once, and the facts decide which process fits.
What a Marchman Act Petition Cannot Do On Its Own
A petition is a request to the court. It does not order treatment by itself. A judge must first find that the statutory criteria are met. The law asks for a good faith reason to believe the person is substance abuse impaired and has lost the power of self-control with respect to substance abuse.
The person must be unable to appreciate the need for help and make a rational choice about it, or be likely to neglect self-care in a way that poses a real and present threat of substantial harm. It must also be unavoidable without treatment. Refusing help alone is not, by itself, evidence of lacking judgment.
The standard of proof is high. The court may order treatment only when the conditions are proved by clear and convincing evidence, which is a demanding standard. Under Florida law, the court must schedule a hearing on the petition within 10 court working days unless a continuance is granted. The court must schedule one within 10 court working days unless it grants a continuance.
What the Petition Cannot Be Used to Accomplish
General information about involuntary treatment petitions can help you prepare questions for a consultation. A Marchman Act petition is not a divorce, custody or child support tool. Those questions move through family court under their own rules.
It also does not treat a mental health condition on its own. The criteria center on substance use, or a substance use disorder that comes with a co-occurring mental health disorder.
A court order does not last forever. Appointed counsel represents the person until the petition is dismissed, the court order expires, the person is discharged from involuntary treatment services, or the court otherwise discharges counsel. When the conditions end sooner, the person must be released. At the conclusion of the 90-day period of court-ordered involuntary services, the respondent is automatically discharged unless a motion for renewal of the involuntary services order has been filed with the court. A court order also does not ensure lasting recovery.
The Safeguards That Protect the Person Being Petitioned
The person named in a petition is called the respondent. The respondent keeps real protections, and the statute builds them in. A copy of the petition and the hearing notice must go to the respondent; the respondent’s parent, guardian, or legal custodian, in the case of a minor; the respondent’s attorney, if known; the petitioner; the respondent’s spouse or guardian, if applicable; and such other persons as the court may direct. Fla. Stat. § 397.68151
When a petition is filed, the court must immediately determine whether the respondent has a lawyer or whether appointing counsel for the respondent is appropriate. Under Florida law, the respondent has the right to counsel at every stage of the court proceeding on the petition, and a respondent who wants counsel but cannot afford a private lawyer has the right to court-appointed counsel. Hillsborough County v. Albrechta
Judges must stay neutral. In J.C. v. State, the Fifth District reversed an order where the judge questioned the only witness after the petitioner was absent. A Fourth District decision in J.J.J. v. D.G. reached a different result, so treat that rule as Fifth District law, not a statewide rule.
Common Fears About What Happens If Nothing Changes
A petition is one option. It does not fix money trouble or decide whether a marriage survives. The right path turns on your spouse’s condition and your household’s facts.
On the children, the judge hears testimony from family members familiar with the person’s history. You may be asked to share what you have seen. That can feel heavy, but it is how the court learns the facts.
On costs, a clerk’s filing fee and service of process fees may apply to a petition, and we can review what could apply to your situation. The court may prohibit, or a law enforcement agency may waive, any service of process fees if a petitioner is determined to be indigent.
Two mistakes show up in the case law. The first is filing in the wrong county. A petition belongs in the county where the person is located. The usual fix for a wrong-county filing is transfer, not dismissal. J.P. v. J.N.
The second is a thin petition. A 2024 Second District decision held that an ex parte order, entered before the respondent is heard, was wrong because the petition did not give a good faith reason to believe the criteria were met. D.H. v. K.J.R.
